SPLECIFICATIQN forming part of Letters Patent No. 656,460, dated August 21, 1900. A pplioatiop filed lVlalcli 22, 1900. Serial No. 9,796. (No model.)

To all whom t mag/concern:

Beit known that we, MARGARET KENNEDY and ANN ELIZA KENNEDY, citizens of the United States, residing at Tlz-icubaya, Mexico city, Republic of Mexico, have invented certain new and useful Improvements in Heating-Drums, of which the following; is a specification. l

This invention relates to new and useful improvements in heating-drums; and its primary object is to provide a heatingdruln of neat, simple, durable, and cheap construction capable of utilizing waste heat for cooking and heating purposes and which, if desired, may be readily so arranged as to permit the use of fuel therein.

To these ends the invention consists in the novel construction and combination of parts hereinafter more fully described an delai med,

and illustrated in the accompanying draw`` ings, showing the preferred form of our invention, and in which- Figure 1 is a perspective view of the heatingdrum. Fig. 2 is a plan view of the device with the top removed. Fig. 3 is a central ver tical longitudinal section.

This heating-drum has the appearance of' an ordinary rectangular range, and its wallsl are formed of any suitable material, as cast or sheet iron. drum is provided with a layer of some heatretaining material, as ashes 3, covered by a preferably metal shelf 4, ahczircularfwalled passage 5 being formed insaid bottom,shelfA and the ashes therebetween, for the reception of a stovepipe 6, which may be extended from A a stove of ordinary construction arranged therebelow or adjacent thereto. A above the shelf 4c and in a plane parallel therewith is a metallic pariition or lcor 7, extending over the entire; length andvwidth of the stove and forming the lower chamber or flue 8 and the upper or main chamber 9.

This floor is provided at a point directly above The bottoin2 of the heatingr' At a point` damper`-16, which may be operated in any f suitable manner,` as by means of an arm 17.

At a point to the rear of the center of the passage 15 a rectangular receptacle 18, of sheet-iron or wire-gauze, is secured by means of screws adapted to engage with projections 19 thereon. This receptacle is adapted to be filled with ashes or other heat-retaining material 3, and a lid 20 is provided,whereby the `contents of the box are readily accessible.

A receptacle 2l, similar to the one above described, is secured to each side wall and to the iioor adjacentthe passage 15. A pipe, as 22, is secured to the top of the heating-drum at a point directly above the opening 10, and openings may be arranged as desired in said top and provided with covers 23. The front of the heating-drum may be provided with a hearth 24, arranged on a line with the floor 7, and a door 25 of ordinary construction is mounted thereabove. A smaller door 26 is hinged' to the heating-drum at a point between the bottom 2 and the shelf 4c therein, thereby permitting the ashes 3 to be readily removed from or placed in position. If desired, a fender-2G may be secured around the .heating-drum. .y

In operation smokeVhotair, dre., passing from a stove on a lower licor of a house are "conducted through a pipe 6 to the flue 8. If the plate 12 is in position over the opening 10, the gaseous products will pass forward in said iiue, up through the passage l5, over and uaroundthe receptacles 1S and 2l, and out through the pipe 22. It will be understood that as the hot air, the., pass over the shelf e and over andlbetween the receptacles 1S and 21 heat will be imparted thereto, and this heat will be retained and slowly given oft by the ashes 3, thereby increasing the efficiency of the heating-drum. A Althoiigh ourheating-drum is especially adapted to be heated byjwalste heat, as here- 'inbefore described, fuel can be burned therein if desired. sary to place a small grate of ordinary construction upon-the fioor 7. Y

lt is obvious that by regulating the plate 12 the gas from the lower stove may be directed either through the due Suor directly from pipe 6 to pipe 22. In the former case therewould be sufficient space between the upper edge of To do this, it is merely neces- IOO theplate 12 and the top of the heating-drum to permit the gaseous products of the combustion of vfuel within the stove to pass therebetween and out into pipe 22. l

In the foregoing description we have shown the preferred form of our invention; but we do not limit ourselves thereto, as We are aware that modifications maybe made therein Without departing from the spirit or sacrificing the advantages thereof, and we therefore reserve the right to make such changes as fairly fall Within thescope of our invention.

Having thus described our invention, whatl We claim as new, and desire to secure by Letters Patent, is l l. In a heating-drum having an inlet and an outlet, the combination with the casing, of a partition therein intermediate the inlet and outlet and having openings therein, dam# pers to said openings whereby the products of combustion may be permitted to flow directly to the outlet or caused to flow indirectlythereto, receptacles detachablysecured upon the partition, and heat retaining material within said receptacles.

2. In a heating-drum having an inlet and an outlet, the combination with the casing, of a partition therein intermediate the inlet and outlet and having openings therein, dampers to said openings whereby the products of combustion may be permitted to fiow directly to an outlet or caused to fiowindirectly thereto, powdered orgranular heat-retaining material upon the bottom of the casing, a cover therefor, receptacles detachably secured upon the partition adjacent to the sides and to the dampered opening, removable lids to the receptacles, and a powdered orgranular heat-retainin g material Within said receptacles.

3. In a heating-drum having an inlet and an outlet, the combination with the casing, of a partition therein intermediate the inlet and outlet and having openings therein near each end, one of said openings in alinement with the inlet and outlet, a door adjacent to the second opening, dampers to the openings whereby the products of combustion may be permitted to iiow directly to the outlet or caused to How indirectly thereto, powdered or granular heat-retaining material upon the bottom of the casing, a cover therefor, receptacles detachably secured upon the partition adjacent to the sides and to the dampered 'openin gs, a removable lid for each receptacle,

and a powdered or granular heat-retaining material within the receptacles.

In testimony whereof We affix our signatures in presence of two witnesses.
